DESCRIPTION:
A vulnerability has been discovered in AhnLab V3 Internet Security,
which can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to an error in the "AhnRec2k.sys"
kernel driver when processing IOCTLs and can be exploited to gain
escalated privileges by sending a specially crafted 0x8101261C
IOCTL.

Successful exploitation allows execution of arbitrary code in the
kernel.

The vulnerability is confirmed in AhnLab V3 Internet Security 8.0.2.6
(Build 630) and AhnRec2k.sys version 1.2.0.3 and is reported in AhnLab
V3 Internet Security 8.0.3.28 (Build 746) and AhnRec2k.sys version
1.2.0.4. Other versions may also be affected.

SOLUTION:
Restrict access to trusted users.
